CHARLES FIN NEGAN, OF FAIRHAVEN, WASHINGTON.

- COMBINED RESAW AND BEVEL-SIDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 737,832, dated September 1, 1903.

Application filed February 3, 1903. Serial No. 141,722. (No model.)

T0 aZZ whom, it may concern.-

Be it known that I, CHARLES FINNEGAN, a citizen of the United States, residing at Fairhaven, in the county of Whatcom and State.

of Washington, have invented certain new and useful Improvements in a Combined Resaw and Bevel-Siding Machine, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to improvements in rcsaw or edger machines; and its object is to provide changeable means to the machine for cutting either boards or bevel siding.

The invention consists in the novel arrangementand adaptation of devices and combinations thereof, as will be hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure l is a side elevation, and Fig. 2 an end elevation, of a machine embodying my invention; and Fig. 3 is a plan view,partly broken away,of the same. Figs. 4, 5, and 6 are enlarged perspec tive views of parts of the invention.

Referring to the drawings, 1 represents the frame or husk of the machine; 2 2, saws which are respectively secured to collars 3 of arbors 4 4, arranged longitudinally of the frame, so that the saws will project over the front of the frame, as shown. The ends of the arbors opposite the saws are eccentrically mounted in cylindrical bushings 5 5 of boxes 6 6. Journal-boxes 7 7 are provided for the arbors adjacent to the said saws and are pivotally mounted by trunnions 8 to upwardly-projecting wings 9 of chair-supports 10, whereby a limited longitudinal oscillation may be given to said shafts about said trunnions. Betweenset-collars 11 of arbor 4. is the sleeve-socket 12 of a shifter-arm 13. Extending downwardly from the said arm is a vertical key 14, adapted to register with notches 15 of a rack-frame 16, firmly secured to the husk.

Any suitable driving mechanism may be adopted, it being preferable, however, to drive from below, as shown, in which 17 is the driving-pulley with tightener-pulley 18, which through the belt 18 serve to drive the pulleys 19 19, mounted on said arbors.

20 represents the stock, which is supported by head blocks 21, provided with suitable dogging devices and set-works, and is carried by carriage 22, traveling on track 23, by action of suitable feed appliances. (Not shown.)

The operation of the invention is as follows:

The saws and the axes of their arbors being supposed to be in the same planes, respectively, when it is desired to cut the stock or cant into boards having parallel faces the saw 2 and its abror 4. are moved back a distance equal to the thickness determined upon for the outer board by raising the shifterarm, so as to lift its key out of one of the notches 15 and while in its raised position pushing upon the arm longitudinal of the arbor, when the key is forced down into a corresponding notch. The cant has meanwhile been moved outwardly or toward the saws by the set-works of the carriage a distance equal to the combined thicknesses of the boards and the saw-kerf and the carriage started on its forward travel. When it is desired to cut the cant into bevel siding, the saws are moved into alinement and thence tilted to oppositely-inclined planes (see Fig. 1) by giving a partial rotation to the aforesaid eccentric journal bushing of each arbor by means of the lever-handles 24 thereof, which handles when moved to the set positions are engaged in notched supports 25. The cant would be moved forward, as before described, for each successive couple of cuts by the set-works. The changes of the saws and set ofcants can be accomplished on the return or gig travel of the carriage, thus entailing no loss of time in the manipulation of the machine, which can quickly be changed from a board-edge to a bevel-siding machine.

It may be remarked that after being sawed the several pieces are surfaced in a planer, but being no part of the invention requires no further mention here.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine of the class described, the combination of arbors, saws mounted thereon, chain-supports, journal-boxes provided with trunnions mounted therein and forming pivotal bearings for one end of said arbors, eccentric bushings for the opposite end of said arbors, boxes for the reception of said bushings, operating-levers on said bushihgs, and

combination of two saws, an arbor for each of said saws, means for changing the pitch of 15 said saw, and means for moving one of said arbors longitudinally within one of the said first-named means, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature 20 in presence of two witnesses.

CHARLES FINNEGAN.
